#### Presentation Transcript

**1. **Equivalent Fractions or
“Half of one,
Six twelfths of the other”

**2. **What is a fraction? A fraction is part of a whole that is made up of equal parts.

**3. **Part of a whole what? Well, it could be part of a whole object, like the proverbial pizza . . .

**4. **Was there something else? Yes, it could also be part of a whole group of items.

**5. **So, what are equivalent fractions? Well, sometimes an object or a group of items can be divided differently, and fractions can name the same amount.

**6. **Say, what? Okay, try this. Let’s take a rectangle and divide it into 8 parts.

**7. **I’m with you. What’s next? Now, let’s take that same rectangle and divide it into 16 parts.

**8. **So that means? So that means 2/8 is equivalent to 4/1 .

**9. **Give us another example. Okay, how about:

**10. **How do you find equivalent fractions? You can multiply (or divide), but you must multiply (or divide) both the numerator AND denominator by the same number.

**11. **What about dividing? Here’s how.

**12. **What if you’re not sure? Here is how you can check to see if two fractions are equivalent.
You can “cross-multiply.”

**13. **How do you know if they’re not equivalent? Here is an example. You still “cross-multiply.”

**14. **Now what? Let’s do some practice activities in the computer lab.
Here’s an activity we will do.

**15. **Open MY COMPUTER.
Here’s what!

**16. **Go to the X DRIVE.
Then…

**17. **Navigate to our class folder
(Class Files ? 5th Grade ? Postman).

**18. **Navigate to our class folder
(Class Files ? 5th Grade ? Postman).

**19. **Navigate to our class folder
(Class Files ? 5th Grade ? Postman).

**20. **Navigate to our class folder
(Class Files ? 5th Grade ? Postman).

**21. **It will look something like this.

**22. **Go to VIEW and add a header for your name. Save on the N DRIVE. Save every few minutes.

**23. **Highlight all the cells you need to shade for the first fraction on the first table.

**24. **Right click on the highlighted cells and choose BORDERS AND SHADING…

**25. **Make sure it says APPLY TO: CELL. Then choose a color. Click OK.

**26. **Then, shade the second fraction on the second table.

**27. **Continue until you have completed all the examples. On some you will need to complete one or more of the fractions. Just click where the number goes, and type.

**28. **On the last one, you need to create your own tables. Go to TABLE on the menu bar. Drag down to INSERT. Drag across to TABLE.

**29. **Choose the number of columns and rows you will need.

**30. **Save and print when you are done.
Are there any questions?
I’ll give you the written directions in the lab.
Let’s go!
